Tooth and Mouth Problems

I am having pain on the right side of the teeths. I had root canal treatment done in 2013. It's been 11 years now. What could be the reasons?

Hello, I consulted a dentist and it was marked that I have pockets in pre molar teeth and so is the reason I have having high sensitivity and mild pain . Doctor mentioned there may be debris and by cleansing it should go away . But last in 2017 I did a cleansing and post that I started getting pain and sensitivity in cheek and chin portion. Please suggest if I should go for a cleansing .

Sharp Tooth sensitivity on the upper molar for almost 2 months( while chewing hard to semi hard foods on that composite filled area, mild sensitivity to cold or hot foods even water that lingers for 3-4 secs). Sensitivity lasts for a few seconds only and often adjacent tooth also gets sensitive with it. I went to the dentist and had my bite adjusted still no improvement and I am currently taking neurobian forte for 20 days. The cavity was not that deep as it was diagnosed clinically and not detected in my xray. What should be my next steps? Is it serious? Or will it resolve on its own?

I completed root canal in upper molor tooth. Is it necessary to go for cap. Is there anynother alternative ti cap. If cap is the best way which cap is good. Metal+seramic or full ceramic (zirconia). Experts kindly advice.

Hi Doctors, From the past week I am having some sensitivity on my front three lower right teeth, and also, there is some discomfort/mild pain continuously there. Now, the pain is not at the root or gums but somewhere between the center and lower third quarter of the teeth. I am using sensodyne toothpaste, which does help in sensitivity but not completely. Can you please suggest to me what would be causing the pain and what can be done to cure it.

Recently i did scaling of my teeth, i found there are two black marks in my tooth probably cavities, as it appeared very preliminary stage. What toothpaste should i use ..?? So that it doesn't expand and also it gets cured
